Omc rod length

[jeff ruth]

Can someone here tell me the difference in the length of the omc 70 hp 3 cylinder rod and the big twin rod? And also is the wrist pin the same diameter

Jeff, I don't have a rod from a "fishing motor" 70 loose to take picture of for you but I do know that the Big Twin rod is longer. The wrist pins are not the same diameter.

Jeff:
I have done some measuring and here is what I have found. The long rod measures 4.75" long and the short (70hp) measures 3.70". That is measured from the center of the wrist pin to the center of the crank journal. The long rod wrist pin hole measures .935" diameter and the short rod measures .875" diameter. The crank end diameters are both 1.5"
Hope that helps.....john sharp, 8H
